King County Road Services is closely monitoring ground movement on 356th Drive SE near Fall City, where a slow-moving slide is taking place under the roadway.

The county does not expect the slide to affect State Route 202.
Tuesday, February 25, 2020
King County will close 356th Drive SE to all vehicle traffic from 8:30 a.m. until 5 p.m. today through Thursday, February 27, for soil testing work. Residents may park a vehicle on the other side of the closure while crews are working, and crews will allow limited access for foot and bicycle traffic throughout the day. Please note: The evacuation route that was put into place earlier this month is on private property, and will not be available for residential use when 356th Drive SE is closed for soil testing this week. The county will maintain access for life and safety emergency response vehicles while crews are working.
